There’s going to be another attempt to launch this flight from Bristol this Monday, May 8 between 0500 and 0530 BST [0400-0430 GMT]. This is weather permitting, but the forecast looks okay at the moment.

This launch is using a 1.9m envelope and longer payload train, and so there’s a NOTAM in place. This tracker has a Raspberry Pi Zero V1.3 attached, which transmits images when solar power is available. It’s a different design to our launch last August; in this case the tracker will continue to operate even if the pi fails. For the curious the ‘pi status’ telemetry values are: 0 = off, 1 = on, 2 = PITS started, 3 = SSDV started).

There will hopefully be a cutdown mounted between the balloon and the tracker. We’ll be testing the 434 MHz uplink to this whilst it’s still in range of Bristol; if it returns over the UK at a convenient time and place we will attempt to trigger the cutdown.

Richard M0SBU who is involved in the UBSEDS project took the amateur radio training courses run by the Chelmsford Amateur Radio Society (CARS) at Danbury in Essex. Further information on the courses is available from the CARS Training Coordinator, Christopher G0IPU
